Plas Johnson is a 6'0", 170-pound wide receiver from Scottsdale, Arizona, who attended Chaparral High School. A three-star recruit in the 2024 class, Johnson was rated as both an athlete and receiver by major outlets, with Rivals ranking him No. 32 nationally at athlete and No. 14 in Arizona. At the college level, Johnson maintained his redshirt during his freshman year in 2024 while appearing in ASU's final four games primarily on special teams. He recovered an onside kick in the second quarter against BYU that led to a touchdown and a 14-0 lead, and finished with three tackles on the season. Johnson missed all of 2025 with a spring ball injury and is a redshirt sophomore returning to the roster.
